Chrysanthemum plant named ‘Dreamy Yolynn’

ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Dreamy Yolynn’, characterized by its upright and mounded plant habit; freely branching habit; uniform and freely flowering habit; decorative-type inflorescences; creamy yellow-colored ray florets; and natural season flowering in early October in the Northern Hemisphere.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Chrysanthemum×morifolium cultivar Dreamy Yolynn.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum×morifolium,commercially known as a garden-type Chrysanthemum and hereinafterreferred to by the name ‘Dreamy Yolynn’.

The new cultivar is a product of a mutation induction program conductedby the Inventor in Fort Myers, Fla. The objective of the program is tocreate new garden-type Chrysanthemum cultivars having inflorescenceswith desirable inflorescence forms, attractive floret colors and goodgarden performance.

The new Chrysanthemum originated by exposing unrooted cuttings of theChrysanthemum cultivar Peachy Lynn, disclosed in U.S. Plant Pat. No.8,892, to X-ray radiation in July, 1998 in Fort Myers, Fla. Followingthe radiation treatment, the cuttings were rooted and terminal apiceswere removed (pinched) three times to promote lateral branchdevelopment. After lateral branches from the third pinch reachedsufficient size, terminal cuttings were harvested, planted and floweredin a controlled environment in Fort Myers, Fla. The new Chrysanthemumwas discovered and selected by the Inventor as a single flowering plantwithin this population in January, 1999. The selection of this plant wasbased on its desirable inflorescence form, attractive ray floret colorand good garden performance.

Asexual reproduction of the new cultivar by terminal cuttings taken in acontrolled environment in Fort Myers, Fla. since March, 1999, has shownthat the unique features of this new Chrysanthemum are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Dreamy Yolynn has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Dreamy Yolynn’. These characteristicsin combination distinguish ‘Dreamy Yolynn’ as a new and distinctcultivar:

1. Upright and mounded plant habit.

2. Freely branching habit; dense and full plants.

3. Uniform and freely flowering habit.

4. Decorative-type inflorescences.

5. Creamy yellow-colored ray florets.

6. Natural season flowering in early October in the Northern Hemisphere.

Plants of the new Chrysanthemum are most similar to plants of the thecultivar Peachy Lynn. In side-by-side comparisons conducted in FortMyers, Fla., plants of the new Chrysanthemum differed from plants of thecultivar Peachy Lynn primarily in ray floret coloration as ray floretsof the cultivar Peachy Lynn are coral in color.

Plants of the new Chrysanthemum can be compared to plants of the thecultivar Lynn, disclosed in U.S. Plant Pat. No. 8,171. In side-by-sidecomparisons conducted in Fort Myers, Fla., plants of the newChrysanthemum differed from plants of the cultivar Lynn in the followingcharacteristics:

1. Plants of the new Chrysanthemum flowered about one week earlier thanplants of the cultivar Lynn when flowered under natural seasonconditions.

2. Ray florets of the new Chrysanthemum and the cultivar Lynn differedin ray floret color as ray florets of the cultivar Lynn were lightpurple.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart, 1995 Edition, except where generalterms of ordinary dictionary significance are used. The followingobservations and measurements describe plants grown in an outdoornursery in Pendleton, S.C., under natural season conditions andpractices which approximate those generally used in commercialgarden-type Chrysanthemum production. One rooted cutting was planted ina 16.5-cm container in late July, 2002. Plants were not pinched, thatis, the terminal apex was not removed to enhance branching. During theproduction of the plants, day temperatures ranged from 29 to 32° C. andnight temperatures ranged from 16 to 21° C. Measurements and numericalvalues represent averages for typical flowering plants.
